ICS570BI Equivalent & Substitute Parts

Part Overview

The ICS570BI is a Fanout Distribution, Spread Spectrum Clock Generator, Zero Delay Buffer IC manufactured by Renesas Electronics Corporation. This 8-SOIC surface mount device operates at frequencies up to 170MHz with a 1:2 input-to-output ratio and features integrated Phase-Locked Loop (PLL) functionality with divider and multiplier capabilities.

The ICS570BI is classified as Obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this clock distribution architecture.

Substitute Part Grouping Explanation

Substitution for the ICS570BI is determined by strict equivalence across the following critical parameters:

• Identical package type: 8-SOIC (0.154", 3.90mm Width)
• Matching functional architecture: Fanout Distribution with Spread Spectrum Clock Generator and Zero Delay Buffer
• Equivalent frequency specification: 170MHz maximum
• Identical input-to-output ratio: 1:2
• Matching supply voltage range: 3.15V ~ 3.45V
• Identical PLL, divider, and multiplier functionality
• CMOS output configuration

The substitute parts 570BILF and 570BLFT meet these electrical and mechanical criteria. Both are manufactured by Renesas Electronics Corporation within the ClockBlocks™ series and maintain functional and pinout compatibility with the ICS570BI.

Parameter Comparison

Engineering Selection Recommendations

Both 570BILF and 570BLFT are active production alternatives to the obsolete ICS570BI. Selection between these substitutes is based on the following factors:

570BILF is suitable for applications requiring the extended operating temperature range of -40°C ~ 85°C, matching the original ICS570BI specification. This part is supplied in Tube packaging and carries ROHS3 compliance certification.

570BLFT is the manufacturer-recommended substitute and is supplied in Cut Tape (CT) & Digi-Reel® format. This part operates within the 0°C ~ 70°C temperature range and carries ROHS3 compliance certification. Selection of this part requires confirmation that the application operating temperature does not exceed 70°C.

Both substitute parts maintain electrical equivalence and are pin-compatible with the ICS570BI. The choice between them depends on temperature requirements and packaging format compatibility with assembly processes.

Frequently Asked Questions (FAQ)

Q: Are 570BILF and 570BLFT electrically identical to ICS570BI?

A: Both substitute parts maintain identical electrical specifications including frequency (170MHz), supply voltage (3.15V ~ 3.45V), input-to-output ratio (1:2), and functional architecture (Fanout Distribution with Spread Spectrum Clock Generator and Zero Delay Buffer). The primary difference is operating temperature range for 570BLFT.

Q: What is the key difference between 570BILF and 570BLFT?

A: The operating temperature range differs. 570BILF operates from -40°C ~ 85°C, matching the original ICS570BI. 570BLFT operates from 0°C ~ 70°C. Additionally, packaging format differs: 570BILF is supplied in Tube, while 570BLFT is supplied in Cut Tape (CT) & Digi-Reel®.

Q: Are these parts pin-compatible with ICS570BI?

A: Yes. Both 570BILF and 570BLFT use the identical 8-SOIC (0.154", 3.90mm Width) package and maintain functional pinout compatibility with ICS570BI.

Q: Do the substitute parts meet RoHS requirements?

A: Yes. Both 570BILF and 570BLFT carry ROHS3 compliance certification, whereas the original ICS570BI is RoHS non-compliant.

Q: Which substitute should I select for my application?

A: If your application operates within 0°C ~ 70°C, either part is suitable. If your application requires operation below 0°C or above 70°C, select 570BILF. Consider packaging format requirements: 570BILF (Tube) or 570BLFT (Cut Tape & Digi-Reel®).
